TPS62A02 and TPS62A02A Step-Down Converter Evaluation Module User's Guide

Abstract

This user’s guide describes the characteristics, operation, and use of TI's TPS62A02 and TPS62A02A evaluation modules (EVM). These EVMs are designed to help the user easily evaluate and test the operation and functionality of the TPS62A02 and TPS62A02A buck converters. The EVMs convert a 2.5-V to 5.5-V input voltage to a regulated 1.8-V output voltage that delivers up to 2-A maximum. This user’s guide includes setup instructions for the following:

1 Introduction

The TPS62A02 and TPS62A02A are synchronous step-down buck DC-DC converters optimized for high efficiency and compact solution size. The TPS62A02 and TPS62A02A delivers an output current up to 2 A. The TPS62A02A variant operates in forced PWM mode (FPWM) across the whole load current range. The TPS62A02EVM-197 and TPS62A02AEVM-197 are available in a 1.6-mm × 1.6-mm SOT563 package.
